This is causing me problems with implementing bit
bashed sysfs gpio on armhf (in this case a beagle bone black and
derivative) i.e. type = "linuxgpio"
attempting to configure GPIO line 45 failed with the error message:
"pin must be in the range 0-31"

Many thanks for all your hard work.

THE FIX:
The definition HAVE_LINUX_GPIO is used to set PIN_MAX between either 31
(default) or 255, however it is called HAVE_LINUXGPIO in the rest of the
codebase.
